Older Cruiser FJ60?

I'm looking for an older land cruiser somthing in the range of 1986...1990..

Got a few questions...

I'm new to the land cruiser world so I may mix up some of the model names, but I'm looking for the SUV type, 4 door, larger body style that looks somewhat like the 4runners...

Are all the land cruisers (FJ60 types...4 door larger one like the body style of the 4runner) solid front axles?

Are all of them full time four wheel drive?

Can you buy electric lockers or air lockers, or other limited slip for the front axle and the rear....? my assumption is that yes you can but anyone in the know? and do the year models make a difference?

I want something with a solid front axle that's a real 4 wheel drive vehicle, I would prefer selectable 4 wheel drive, but do want the ability to setup some lmited slips or selectable lockers on the front and rear.

I've heard the the land cruiser is one of the best. Any web sites to check out or any tips on what to look for, or to stay away from.

Appreciate any comments....you can email me at elbert.clarke@adelphia.net** (remove the ** to email).

Also would want a model where there were plenty of aftermarket parts, like winch bumpers, mounts, suspension mods, maybe heavy duty shocks..etc lights, ...whatevers....
